Also, the user will need to enable 3rd party repositories they may have been using prior to the upgrade. They can be found on the “Other Software” tab shown in the first screenshot for step #3 above. Best to check there beforehand to see what is enabled prior to upgrade.

Actually during upgrades, the system first attempts to download the packages. You can see that on the 6th screenshot. “Getting packages”. If this step fails, the system will automatically revert any changes. In case the networking stops after this step, the upgrade will proceed in offline mode as all the required packages are already downloaded on your computer.
